Take it to the Antique Fisherman. He has parts and also does repairs. The worm gear went out on mine and it turned out to be the little metal piece that feeds the line guide to the worm gear. I went to antique fisher man, across the street from buned out KC's Cabbose. The man had the parts on hand for 3 bucks, so I bought 3 more for back up on my other reels. Very cool Old guy, But said he is about ready to give it up. Highly recomended.
GOODLUCK.........
